If you are setting up your own modem on a One NZ Fibre, VDSL or ADSL broadband plan and you are unable to get online, you may need to change your modem settings.
Before you begin
Note: ADSL/VDSL is no longer sold by One NZ as of 1 October 2025.
Check your modem is compatible with the broadband service you are connecting to, if you are connecting to:
- Fibre, your modem must support WAN VLAN tagging with IPoE
- VDSL or ADSL, your modem must support New Zealand PPPoA DSL
Check you are on a broadband only plan
If you have voice calling over broadband, you will need to use the latest One NZ supplied modem. If your non-One NZ modem has SIP voice calling capability, this cannot be used on the One NZ network.
You'll find our set up voice calling guide over here
.
Take a look at our set up guide here .
